The problem of product distribution becomes an important topic in a company's transportation system. PT Amanah Prima Indonesia (API) is a national-scale company engaged in the production of juice drinks. With the number of consumers scattered in the Semarang area, it is necessary a solution in the distribution of products in order to obtain operational efficiency. The method used is Nearest Neighborhod Algorithm. The results obtained are: (a) Distance savings of 144.20 Km or 40.06%, (b) Product distribution time can be reduced for 5.15 hours or 30.31%, (c) Fuel costs used obtained cost savings of Rp.108.150, - or equal to 40.06%, (d) Expenses for driver and companion cost is no difference of Rp.600.000, -, and (f) The total cost of distribution is obtained savings of Rp. 108,150 or 12.43%.

The population of Sidoarjo Regency with a relatively high number and growth rate has consequences for the increase of waste produced volume. Increasing of volume waste is directly proportional to the increase in population, meaning that amount of waste produced is increasing (organic and inorganic waste). The TPA center in one of the garbage collection locations in Sidoarjo Regency has exceeded capacity (overload). This research was conducted with the aim of describing initial model of the distribution of waste used, evaluating initial performance model of waste distribution in Sidoarjo Regency, and providing recommendations to propose improvements in the waste distribution model used. The method applied in this study was using simulation. Based on the simulation results, the Third Scenario proposed the route with the most efficient distance, this affected the vehicle's operational time and the operational costs needed.

Transportation problem is just like inventory, this is an activity in logistics area. This activity is possible to make some production in one place and to consume them in another place. The aim of this research were to evaluate the existing network distribution model performance and to provide sugestions to proper the network distribution model used. The applied metode to achieve the goal was Nearest Neighbor Algorithm. The results were: (a) Distance saving was 538,2 Km or 26,59%, (b) Distribution time of product could be reduced to 9,37 hours or 19,07%, (c) Fuel cost could be reduced to 403.650 rupiahs or 26,59%, (d) Driver and assistance cost could be saved to 272.850 rupiahs or 4,5%, and (f) Total of distribution cost could be saved to 676.500 rupiahs or 25,71%.

Pond is one place that is used as a place to cultivate fish, shrimp, and other aquatic animals that can live in brackish water. Changes in water quality upstream and downstream of the pond due to pollutants may affect the ecological balance of waters. Pollutants can be determined by two simple parameters, the biochemical oxygen demand (BOD) and chemical oxygen demand (COD). While the ability to break down pollutants (biodegradability) can be determined using the ratio of BOD/COD. BOD analysis using the Winkler titration method, whereas the COD analysis using titrimetric method. The value of BOD, COD, and the ratio of BOD/COD in the upstream area is 28.00 mg/L, 60.00 mg/L, and 0,467 respectively. While the value of BOD, COD, and the ratio of BOD/COD in the downstream area is 20.00 mg/L, 43.00 mg/L, and 0.465 respectively. Ratio BOD/COD obtained show that the organic pollutants in the pond is biodegradable.

The batik industry in Indonesia is one of the small and medium business sectors (SMEs) which is a source of work for some people. The batik industry produces various kinds of liquid waste, one of which is dyes including remazol dyes. In this research, clay and bamboo charcoal which are activated by HCl 1 M were made into a composite biosorbent with a ratio of clay and bamboo charcoal (80%: 20%). In this study, two variables are used, namely dose and contact time variation. The results of removal efficiency for variable adsorbent doses and contact time respectively were 30.00% and 31.33%. FTIR spectrum analysis shows wave numbers 1338.64 and 1309.71 cm-1 which is the C-H bending region. The peak at wave number 1539.25 cm-1 with strong and tapered absorption is identified as aliphatic C-C strains which are functional groups of activated charcoal. The spectrum gives a clay-charcoal composite specification when the absorption peak at wave number 3462.34 cm-1 there is an interaction between O-H in clay and O-H in charcoal, causing an increase in absorption intensity. The use of clay and bamboo charcoal biosorbent can reduce levels of dyes in batik industry liquid waste.

Sidoarjo Regency is one of the supporting districts of East Java province. Sidoarjo Regency is experiencing rapid progress because of the development and potential in trade and industry. One of the industries often found in Sidoarjo Regency is tofu factory. The rapid number of tofu craftsmen industry has caused an increase in the volume of liquid waste which also flows into water bodies. The purpose of this study was to determine the reduction in BOD and COD levels for the tofu factory wastewater treatment in the Sepande area, Sidoarjo Regency using a contructed wetland with Typha latifolia as the remediator. The research stage will be carried out using a laboratory scale using acclimatization as the adaptation stage of Typha latifolia and a crontructed wetland reactor as phytoremediation processing. Based on the results and discussion, it can be concluded that there was a decrease in BOD and COD levels in the tofu industrial wastewater in Sidoarjo using the Constructed Wetland system. The percentage reduction in BOD content was greatest in soil media with 3 stems of Typha latifolia plants and a detention time of 4 days of 72%. While the largest percentage reduction in COD levels was in soil media with 2 stems of Typha latifolia plants and 4 days of detention time of 84%.

The development of restaurant businesses in Sidoarjo City is quite rapid, and this will of course be accompanied by an increase in domestic waste originating from a restaurant called greywater. Restaurant wastewater contains a lot of organic content and often without prior treatment is discharged directly into receiving water bodies. The purpose of this study was to determine the reduction in BOD and COD levels for the processing of restaurant wastewater using a contructed wetland with Cyperus Rotundus as the remediator. The research stage will be carried out using a laboratory scale using acclimatization as the adaptation stage of the Cyperus Rotundus plant and the crontructed wetland reactor as phytoremediation processing. Based on the results and discussion, it can be concluded that there was a decrease in BOD and COD levels in restaurant liquid waste using the Constructed Wetland System and Cyperus Rotundus plants. The percentage reduction in the largest BOD content in clay media with the number of Cyperus Rotundus plants of 3 stems gave the highest BOD removal efficiency, namely 70% at 4 days of detention time. While the largest percentage reduction in COD levels in clay media with the number of Cyperus Rotundus plants as many as 3 stems gave the highest COD removal efficiency, namely 67% at 4 days detention time.
